Title: Improvements in heat engines particularly internal combustion engines
IPC: F02C7/18
Filed: 1947-09-10
Abstract: 642,145. Gas turbine plant. TAVERNIERS, P. Sept. 10, 1947, No. 24904. Convention date, Sept. 11, 1946. [Class 110(iii)] [Also in Group XII] A turbine A, which drives an air-compressor D, and a useful power turbine B receive working-fluid from the same combustion-chamber. Both turbines exhaust to a radial flow bladed turbine C which also provides useful power. The turbines A, B are similar to overshot water-wheels. The inlet of turbine C is throttled by means of two ported discs which are moved in response, respectively, to variations in the speed of turbine B and the pressure of the combustion chamber delivery. The combustion chamber, Fig. 16, has a pilot burner and two burners 47 of refractory material. A mixture of air and fuel is injected into the burners and issues through a number of slots. Combustion is started by a heater 50 and thereafter the burners become incandescent. Secondary air is delivered to an annular chamber 81 and passes through a double jacket wall, down then up, to a ring of ports 82 through which it passes to mix with the products of combustion. Measured quantities of a combustible mixture are delivered by devices F<SP>1</SP>, F<SP>2</SP> and corresponding quantities of secondary air by devices G\ G<SP>2</SP>. These devices are operated by cams on a shaft driven by turbine A; the devices F<SP>1</SP>, F<SP>2</SP>, and consequently the burners 47, operating alternately. The gases go by ducts 57<SP>1</SP>, 57<SP>2</SP> to turbines A and B. One of the devices F is shown in Fig. 7. A variable stroke piston 21, which is positively depressed by a lever 25, is moved upwards by the pressure of the air entering past a cam-actuated valve 80. Fuel under the same pressure from an injection pump enters through pipe 23. When the piston is depressed the mixture passes out through port 24 and a cam-actuated valve. Thelowest position of the piston is constant and the upward movement is determined by the movement of the cam-operated lever 25 which is varied by moving the pivot of the lever along the slot 34. This movement is effected by connection with an accelerator pedal. Similar devices are used to measure the secondary air. Each fuel injection pump has in one cylinder two plungers of different diameter which reciprocate in opposite phase. They are operatively connected to the pistons 21 of the devices F so that the fuel delivered is proportional to the combustion air. In the plant as applied to a motor vehicle. the compressor turbine A has a free-wheel connection with the power shaft. At low loads the inlet valve 58 of turbine A is closed and the compressor is driven by turbine B. At higher loads the valve 58 is opened by a device responsive to the delivery pressure of the combustion chamber. On depressing the brake pedal the inlet valve 59 of turbine B is closed and the inlet valve 58 of turbine A is opened. The vehicle may have two plants, one coupled to the front axle for forward running and one coupled to the rear axle for reverse running.

Title: Improvements in or relating to resin-coated pulp board and method of making the same
IPC: D21J1/16
Filed: 1928-08-31
Abstract: 319,901. Clark, G. M., (Agasote Millboard Co.). Aug. 31, 1938. Boards; papier mÔchÚ; paper, trea,ting with special materials.-A method of making resincoated pulp board consists in superposing upon one face of a base board of compressed fibres intermingled with a fluxing binder, one or more sheets of fibrous material embedded in fluid artificial resin, a sheet of protective material which will not adhere permanently to the fluid resin, and a piece of " sponge " board consisting of relatively uncompressed fibres intermingled with a fluxing binder, and subjecting the whole to heat and pressure sufficient to render the resin infusible and insoluble and to compact the " sponge " board. The pulp board used has added thereto a fluxing binder such as accaroid resin, but gilsonite, rosin, gum resins, mineral pitch or asphalt may be used. The pulp is run into a mould and partly compressed to remove the water to form the produce referred to as " sponge " board. This board is further compacted by pressure and heat to form a base C, upon which are placed one or more, preferably at least three, sheets E of paper or other fibrous material impregnated with a phenolic or other artificial resin. These sheets E may be applied to both sides of the pulp board. The material is then placed between the platens B of a steam-heated press, with sheets D of partly compacted pulp board, or " sponge " board, ana plates F of steel or copper having a coating of a repellent substance such as stearic acid, interposed between the platens and the impregnated sheets. Heat and pressure are then applid to compact the sponge board and render the artificial resin insoluble. The press is cooled before releasing the pressure. The outermost sheet or sheets of paper E may bear a printed coloured design. The board D act as cushions to compensate for any unevenness in the press or base board, and after compacting, are used as the base board C. Preferably the boards D before use as cushions are dipped into liquid artificial resin.

Abstract: 600,160. Stopping arrangements. DEBRIE, A. L. V. C. Sept. 28, 1945, No. 25288. Convention date, Jan. 30, 1942. [Class 100(ii)] [Also in Group XX] In a continuouslyrunning photographic apparatus for the reproduction of documents, the feed of more than one document at a time is prevented by a shutter, which presses yieldingly against the entry chute of the machine allowing an already partially fed document to be drawn under it but completely preventing the passage past it of an undriven document, and which is tipped open by a servo-control when the first document has passed through the photographing position to allow a fresh document to slide down the chute to be drawn into the machine. As shown a document 1 is being fed by continuously rotating gripping rollers 3, 4 and passes under a contact member 11, to be photographed as it passes from the roller 3 to the roller 5. When the document has completely passed under the member 11 the latter falls into a groove in the roller 3 and causes, by any known means, the shutter 6 to open to the dotted line position allowing a document 14, previously barred by it, to slide down the incline 2 and engage the feed rollers. In a modification the two rollers 3, 5 may be replaced by a single drum.

Filed: 1967-06-01
Abstract: 1,157,232. Envelope feeding; sorting. BELL & HOWELL CO. 1 June, 1967 [6 June, 1966], No. 25431/67. Heading B8R. [Also in Division G1] Apparatus for feeding envelopes comprises platforms tiltable between envelope-receiving and envelope-discharging positions and means for returning a platform to its initial receiving position on discharge of the envelope, the edge of the returning platform serving to lift the trailing edge of the envelope, and guide it towards a hopper. A sorting apparatus is illustrated (Fig. 7) in which platforms 11 are pivotably carried on knife edge members 17 mounted on balance beams 23 which pivot about fulcrums 24, counterbalance weights 31 determining the minimum envelope weight to cause a particular platform to tilt. Fig. 8 shows a sequence in which unsealed, envelopes with their flaps 58 underneath and to the rear are fed on a conveyer in the direction of arrow 59. When the weight of the envelope causes a platform to tilt, the envelope is discharged downwards and to the rear into a guide throat 46 formed by guide plates 43, 44 and hence to the nip 47 between a driven feed roller 48 and an idler roller 49. The envelope, having been pivoted through the vertical plane 73, is then forced out with flap 58, above and to the front of the envelope, so that the leading edge is engaged between the flap and the pocket portion of the top envelope of a stack carried on a receiving tray 61. The idler roller 49 is forced against roller 48 by spring 53, the axis 54 of the former being slightly above the axis 52 of the driven roller, and the roller 48 having longitudinal corrugations 72 to assist gripping and swivelling of the envelope. Hopper (Fig. 7).-Each hopper has a receiving tray 61 carried on a telescopic extension 62 sliding in a guide-way 63, the spring 64 urging the tray yieldably upwards, the effect of the stack of envelopes being to move the tray downwards. The inclination of tray 61 can be altered by adjusting screw 71 which passes through support bar 68 and presses against the tray whilst a leaf spring 69 holds the tray on the support bar.

Filed: 1974-06-10
Abstract: 1469261 Flowmeters MANNING ENVIRONMENTAL CORP 10 June 1974 [27 July 1973] 25678/74 Heading G1N [Also in Division H3] The total flow of water over a V-notch weir or through an open-ended channel is measured by deriving an electric analogue of the water surface level, converting that to a digital signal, non- linearly converting the digital signal by means of a read-only memory 29 to represent volume flowrate and accumulating the flow-rate signal in a totalizer 41 to indicate the total flow volume. The read-only memory can be slotted into the front panel of the apparatus for easy adaption of the meter characteristic to suit different channel sections. The electric analogue is derived by a surfacelevel-seeking probe 25, Fig. 7, which is lowered into the water by motor 53. When the probe contacts the water the motor is automatically reversed until contact is broken. After a 4 second delay, determined by R10, C2, the probe is again lowered. "End-of-reel" and "slack" switches S4, S3 are provided. Motor 53 also moves the wiper of a potentiometer R8, to produce a voltage proportional to the water surface level. Switch S7 allows the gain of amplifier A1 to be selected, X1, X2 or X4. At various predetermined levels, threshold circuits energize light-emittings diodes 57 and operate relays to initiate desired control functions, e.g. chlorination or flow diversion. The rate of operation of a sampler 59, Fig. 6, is selected by decade switch 44 and thumbwheel adjustment 59.
